There are several different types of Bitcoin clients. Server-assisted clients like blockchain.info rely on centralized servers to do their network verification for them. Although the server can't steal the client's bitcoins directly, it can easily execute double-spending-style attacks against the client.

It takes time for the bitcoin community to learn how to secure bitcoin. This is new technologies and many people will lose their bitcoin from here to the future.

true enough but people will still lose them security or not.

People will leave bitcents on wallets and not care if they reformat.

people will back up their wallets and keep the backups inhouse on another machine and lose them all to fire.

there are also paper bitcoins out there. That people sell on college campuses, that are basically the keys to a wallet.. I'm sure these get lost now and then before the college kid figures out bitcoin and transfers them over.

People will leave them on sites all over the place.. i know I have bitcents on more sites than I care to look for.

I guess it isnt a real issue or anything but it is interesting and makes me wonder how many will actually be in circulation in 10 years

it's increasing at 50 BTC per every 10 minutes... trust me the market is flooded with bitcoins now... perhaps more than what can be absorbed due to the fact that it's too hard for people to use them still... yea companies like mine are trying to fix that.. but until we (and others like me) fix it.. it will be limited to us geeks that can use them...

I'm sure grandma knows how to use bitcoins to get stuff at the grill in new york right?

I love when things like this happen, because of the way Bitcoin works, it is in front of all our eyes, and all everyone can do is speculate. Honestly amazing as all hell the smart people behind some of the ventures and random things creating value to Bitcoin, and yet security, the thing we all talk about the most, is the last thing people seem to care about.

They just put in in third party sites (insert the millionth FlexCoin commercial post this week here) rather than educating themselves it seems.
